Ssis 如何停止基于存储过程输出的包执行？

ssis

Ssis 如何停止基于存储过程输出的包执行？,ssis,control-flow,Ssis,Control Flow,我有一个SSIS包，第一个任务执行一个存储过程来验证运行日期不是假日。如果是假日，则返回一个计数为1的记录集如果recordcount为1，我希望能够停止SSI，但如果recordcount为零，则继续运行。我不知道最好的方法来实现这一点。我应该向包中添加什么控制流项我对SSIS比较陌生，所以我不知道要添加什么项目。任何帮助都会很好。这里有一个可能的选项，可以为您提供实现这一目标的想法。该示例通过检查包含假日列表的表来检查今天的日期是否为假日。仅当今天的日期不是假日时，才会执行其余的包任务。

这里有一个可能的选项，可以为您提供实现这一目标的想法。该示例通过检查包含假日列表的表来检查今天的日期是否为假日。仅当今天的日期不是假日时，才会执行其余的包任务。该示例使用

SSIS 2008 R2

和

SQL Server 2008 R2

数据库

逐步过程：

CREATE TABLE [dbo].[Holidays](
    [Id] [int] IDENTITY(1,1) NOT NULL,
    [HolidayDate] [datetime] NULL,
 CONSTRAINT [PK_Holidays] PRIMARY KEY CLUSTERED ([Id] ASC)
) ON [PRIMARY]
GO

CREATE PROCEDURE [dbo].[CheckTodayIsHoliday]
AS
BEGIN

    SET NOCOUNT ON

    SELECT  HolidayDate
    FROM    dbo.Holidays
    WHERE   DATEDIFF(DAY, HolidayDate, GETDATE()) = 0   
END
GO

使用SQL脚本部分给出的脚本创建名为

dbo.Holidays

的表和名为

dbo.CheckTodayIsHoliday

的存储过程。填充表格，如屏幕截图#1所示

在SSIS包上，创建名为

RecordCount

和

SQLProcedure

的两个变量。用屏幕截图2所示的值填充它们。另外，创建OLE DB连接以连接到SQL Server数据库。在本例中，我将其命名为SQLServer。请参阅屏幕截图#3。该示例使用数据源而不是普通连接。这就是为什么图标在屏幕截图中有所不同

在SSIS包上，放置

数据流任务

，并在数据流任务中放置

OLE DB源

和

行计数转换

。请参阅屏幕截图#4

配置OLE DB源代码，如屏幕截图5和6所示。这将执行存储过程并获取结果

配置

行计数转换

，如屏幕截图7所示

在

控制流

上，我又放置了几个虚拟任务，如屏幕截图#8所示

右键单击数据流任务和下一个任务（序列容器）之间的连接器，如屏幕截图#9所示

配置

优先约束编辑器

，如屏幕截图10所示

屏幕截图35;11显示了包的执行情况，日期（

2011年6月16日

）显示在

dbo.Holidays

表中，标记为holiday。当然，2011年6月16日不是我工作的假期，除非我休假

更改表格数据，如屏幕截图#12所示

屏幕截图#13显示了包执行的日期（

2011年6月16日）未出现在dbo.Holidays
表中

一种方法是创建一个执行SQl任务，用于设置变量@Holiday的值。然后，通过右键单击绿线本身并单击编辑，将执行SQl任务的成功流程线同时更改为成功和约束。选择“表达式和约束”作为求值操作，然后为表达式添加一个表达式，如下所示：
@Holiday == 0
